Hi Mr. Person and welcome to Saabscene
At 72k, your 9000 is a relative baby- it's easily capable of three times that if cared for. At such a low mileage there should be no impending significant mechanical renewals required e.g. timing chains normally last at least twice that.
9000s have a reputation in some places for being expensive to maintain. This, however, is normally due to infrequent servicing and a lack of care. Little and often is the key here.
Make sure the manufacturers intervals are rigidly followed. A lot of folk go for a 6000 mile/6 month intermediate service which is beneficial in keeping on top of any little niggles that may occur.
Always us a good quality fully synthetic oil to protect not just the turbo but also enhance engine life.
One immediate recommendation I would have is to check the service history to make sure that recent fluid changes have been carried out. Remember the coolant and brake fluid should be renewed every 2 years. If the coolant doesn't appear to have been renewed within that time, use a radiator flush to make sure you get rid of any unwanted deposits.
Lastly, enjoy!
